Abstract
OBJECTIVE This study aims to determine the preoperative and perioperative risk parameters associated with a decrease in hemoglobin (Hb) in patients undergoing percutaneous nephrolithotomy (PCNL). METHODS We collected prospective data of consecutive patients who underwent PCNL from January 2018 to December 2022. The median decrease in post-operative hemoglobin levels compared to pre-operative was found to be 1.5 g/dl. This value was the cut-off value that divided the sample into two groups. Group 1 has a decrease in Hb levels that is higher or equal to the cutoff, group 2 has a decrease in Hb levels that is lower than the cut-off. All preoperative, stone characteristics and perioperative factors were recorded. RESULTS A total of 273 patients were included in the study, 141 in Group 1 and 132 in Group 2. The mean age of Group 1 was significantly higher (55.48 ± 8.73 vs 45.9 ± 10.75 years, p < 0.05). The mean bleeding of Group 1 was significantly higher (285.85 ± 113.68 vs 135 ± 77.54 ml, p < 0.05). There was a significant difference in mean operation time between groups (86.35 ± 32.05 vs 64.89 ± 27.83 min, p < 0.05). Multivariate analysis showed that the variables age, comorbid diabetes mellitus, intraoperative bleeding amount, and operation time had a significant relationship with Hb reduction in patients undergoing PCNL (p < 0.05). CONCLUSIONS Older age, comorbid diabetes mellitus, large amounts of intraoperative bleeding, and longer operating time are factors associated with PCNL-related postoperative hemoglobin decrease.

Abstract
Percutaneous nephrolithotomy has become the standard procedure for the management of large kidney stones. Compared with other endo-urological techniques, it has a better fragmentation rate in a single session for kidney stones over 20 mm. It is therefore the recommended first-line treatment modality for large kidney stones. Bleeding is a well-known complication of this procedure, often requiring transfusion. In 0.8% of cases, bleeding can be severe, requiring surgical intervention to control hemostasis. Damage to the lumbar artery is a very rare event, and a potential complication. To our knowledge, this is the first report of lumbar artery involvement during percutaneous nephrolithotomy, complicated by severe bleeding and hemodynamic instability, necessitating conversion. Surgical exploration revealed a severed and bleeding lumbar artery. After hemostasis control by coagulation and ligation, the patient became stable. The patient was discharged on D3, where ureteroscopic lithotripsy was planned after collegial discussion with the patient. Based on this experience, it is important for the surgeon to have in mind certain principles and a thorough knowledge of the classic lateral lumbotomy approach to the kidney.

Abstract
OBJECTIVE To assess the effects of tranexamic acid (TXA) in individuals with kidney stones undergoing percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS We performed a literature search of Cochrane Library, PubMed (including MEDLINE), Embase, Scopus, Global Index Medicus, trials registries, grey literature, and conference proceedings. We included randomised controlled trials (RCTs) that compared treatment with PCNL with administration of TXA to placebo (or no TXA) for patients aged ≥18 years. Two review authors independently classified studies and abstracted data. Primary outcomes were blood transfusion, stone-free rate (SFR), thromboembolic events (TEE). We rated the certainty of evidence (CoE) according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach using a minimally contextualised approach with pre-defined thresholds for minimally clinically important differences (MCID). RESULTS We included 10 RCTs assessing the effect of systemic TXA in PCNL vs placebo (or no TXA). Eight studies were published as full text. Based on an adjusted baseline risk of blood transfusion of 5.7%, systemic TXA may reduce blood transfusions (risk ratio [RR] 0.45, 95% confidence interval [CI] 0.27-0.76). Based on an adjusted baseline SFR of 75.7%, systemic TXA may increase SFR (RR 1.11, 95% CI 0.98-1.27). There is probably no difference in TEEs (risk difference 0.001, 95% CI -0.01 to 0.01). Systemic TXA may increase adverse events (AEs) (RR 5.22, 95% CI 0.52-52.72). Systemic TXA may have little to no effect on secondary interventions (RR 1.15, 95% CI 0.84-1.57). The CoE for most outcomes was assessed as low or very low. CONCLUSIONS Based on a body of evidence of 10 RCTs, we found that systemic TXA in PCNL may reduce blood transfusions, major surgical complications, and hospital length of stay, as well as improve the SFR; however, it may increase AEs. These findings should inform urologists and their patients in making informed decisions about the use of TXA in the setting of PCNL.

Abstract
BACKGROUND To demonstrate the technical feasibility of percutaneous nephrolithotomy (PCNL) guided by 5G-powered robot-assisted teleultrasound diagnosis system (RTDS) in a complex kidney-stone (CKS) cohort and present our preliminary outcomes. PCNL is highly skill-required, which hinders it popularization in primary medical units of remote regions. We designed an innovative tele-assistance approach to make PCNL easy to be operated by inexperienced surgeons. METHODS This was a prospective proof-of-concept study (IDEAL phase 1) on intraoperative tele-assistance provided by online urological experts via a 5G-powered RTDS. Total 15 CKS patients accepted this technology. Online experts manipulated a simulated probe to assist unskilled local operators by driving a patient-side robot-probe to guide and monitor the steps of access establishment and finding residual stones. RESULTS Median total delay was 177ms despite one-way network-connecting distance > 5,800 km. No perceptible delay of audio-visual communication, driving robot-arm or dynamic ultrasound images was fed back. Successful tele-assistance was obtained in all cases. The first-puncture access-success rate was 78.6% with a one-session SF rate of 71.3% and without complications of grade III-V. CONCLUSIONS The current technology based on 5G-powered RTDS can provide high-quality intraoperative tele-assistance, which has preliminarily shown satisfactory outcomes and reliable safety. It will break down a personal competence-based barrier to endow PCNL with more popular utilization. TRIAL REGISTRATION The study was approved by ethics committee of the Xinjiang Kezhou People's Hospital and ethics committee of the First Affiliated Hospital of Nanjing Medical University and was registered on http://www.chictr.org.cn (ChiCTR2200065849, 16/11/2022).

The effect of the use of tranexamic acid in percutaneous nephrolithotomy on blood loss and surgical visual clarity: a prospective, randomized, controlled and double-blind study. Urolithiasis 2024; 52:20. [PMID: 38183497 DOI: 10.1007/s00240-023-01520-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 12/06/2023] [Indexed: 01/08/2024]
Abstract
Tranexamic acid, once a randomly used antifibrinolytic agent, has been in standard protocols for many specific surgeries. Studies are still needed to standardize the dose and route of tranexamic acid administration, examine its possible contributions in urological surgery, and establish a protocol for its use. To contribute to this goal, we designed a prospective, randomized, double-blind study on 75 patients with 1 control and 2 study groups (n = 25) who underwent percutaneous nephrolithotomy. Group Tranexamic acid received 10 mg/kg intravenous tranexamic acid preoperatively. And Group Irrigation received the same amount in the initial irrigation fluid. Primarily, we observed the total amount of blood transfusion and the changes in hemoglobin and hematocrit values during 2 postoperative days. Distinctively, we intraoperatively monitored hemoglobin continuously as a saturation hemoglobin value to assess the timing of the effect of tranexamic acid. Secondarily, we questioned surgical visual clarity with a standard visual score to reveal its contribution to surgical practicality, operative time, and residual fragment quantity. Our results revealed a significant difference in the reduction of hemoglobin and hematocrit change and blood transfusion in both tranexamic acid groups concerning control, especially on the second day (p = 0.003, p = 0.002, p = 0.001). Likewise, surgical visual scores were significantly better in both tranexamic acid groups (p = 0.018). In conclusion, intravenous or local administration of tranexamic acid at a dose of 10 mg/kg will be sufficient to maintain perioperative stability in hemoglobin values, use fewer blood products and provide a better visual advantage for the surgeon intraoperatively.The trial registration number is NCT05947435, and the date of registration is 07/07/2023, retrospectively registered.

Abstract
Percutaneous nephrolithotomy (Labate et al.) is the standard procedure for the treatment of large (≥2cm) kidney stones. The patient can be in prone or modified supine position. The puncture is performed under fluoroscopy and/or ultrasound guidance. The stone-free rate seems to be comparable between miniaturized and standard PCNL. Procedures performed with smaller diameter instruments tend to be associated with significant lower blood loss, but longer procedure times. The limitation of the number of percutaneous tracts results in better preservation of the kidney function and lowers the risk of complications. The use of tranexamic acid during PCNL may be interesting for reducing the bleeding risk, the transfusion rate, and possibly the intervention duration. METHODOLOGY: These recommendations were developed using two methods: the Clinical Practice Recommendation (CPR) method and the ADAPTE method, depending on whether the question was considered in the European Association of Urology (EAU) recommendations (https://uroweb.org/guidelines/urolithiasis [EAU 2022]) and their adaptability to the French context.

Abstract
BACKGROUND Percutaneous nephrolithotomy (PCNL) is the gold standard for the treatment of large kidney stones but comes with an increased risk of bleeding compared to other treatments, such as ureteroscopy and shock wave lithotripsy. Tranexamic acid (TXA) is an antifibrinolytic agent that has been used to reduce bleeding complications in other settings. OBJECTIVES To assess the effects of TXA in individuals with kidney stones undergoing PCNL. SEARCH METHODS We performed a comprehensive literature search of the Cochrane Library, PubMed (including MEDLINE), Embase, Scopus, Global Index Medicus, trials registries, other sources of the grey literature, and conference proceedings. We applied no restrictions on the language of publication nor publication status. The latest search date was 11 May 2023. SELECTION CRITERIA We included randomized controlled trials (RCTs) that compared treatment with PCNL with administration of TXA to placebo (or no TXA) for patients ≥ 18 years old. DATA COLLECTION AND ANALYSIS Two review authors independently classified studies and abstracted data. Primary outcomes were: blood transfusion, stone-free rate (SFR), and thromboembolic events (TEEs). Secondary outcomes were: adverse events (AEs), secondary interventions, major surgical complications, minor surgical complications, unplanned hospitalizations or readmissions, and hospital length of stay (LOS). We performed statistical analyzes using a random-effects model. We rated the certainty of evidence (CoE) according to the GRADE approach using a minimally contextualized approach with predefined thresholds for minimally clinically important differences (MCIDs). MAIN RESULTS We analyzed 10 RCTs assessing the effect of systemic TXA in PCNL versus placebo (or no TXA) with 1883 randomized participants. Eight studies were published as full text. One was published in abstract proceedings, but it was separated into two separate studies for the purpose of our analyzes. Average stone surface area ranged 3.45 to 6.62 cm2. We also found a single RCT published in full text assessing the effects of topical TXA in PCNL versus placebo (or no TXA) with 400 randomized participants, the results of which are further described in the review. Here we focus only on the results of TXA used systemically. Blood transfusion - Based on a representative baseline risk of 5.7% for blood transfusions taken from a large presentative observational studies, systemic TXA may reduce blood transfusions (risk ratio (RR) 0.45, 95% confidence interval (CI) 0.27 to 0.76; I2 = 28%; 9 studies, 1353 participants; low CoE). We assumed an MCID of ≥ 2%. Based on 57 participants per 1000 with placebo (or no TXA) being transfused, this corresponds to 31 fewer (from 42 fewer to 14 fewer) participants being transfused per 1000. Stone-free rate - Based on a representative baseline risk of 75.7% for SFR, systemic TXA may increase SFRs (RR 1.11, 95% CI 0.98 to 1.27; I2 = 62%; 4 studies, 603 participants; low CoE). We assumed an MCID of ≥ 5%. Based on 757 participants per 1000 being stone free with placebo (or no TXA), this corresponds to 83 more (from 15 fewer to 204 more) stone-free participants per 1000. Thromboembolic events - There is probably no difference in TEEs (risk difference (RD) 0.00, 95% CI -0.01 to 0.01; I2 = 0%; 6 studies, 841 participants; moderate CoE). We assumed an MCID of ≥ 2%. Since there were no thromboembolic events in intervention and/or control groups in 5 out of6 studies, we opted to assess a risk difference with systemic TXA for this outcome. Adverse events - Systemic TXA may increase AEs (RR 5.22, 95% CI 0.52 to 52.72; I2 = 75%; 4 studies, 602 participants; low CoE). We assumed an MCID of ≥ 5%. Based on 23 participants per 1000 with placebo (or no TXA) having an adverse event, this corresponds to 98 more (from 11 fewer to 1000 more) participants with adverse events per 1000. Secondary interventions - Systemic TXA may have little to no effect on secondary interventions (RR 1.15, 95% CI 0.84 to 1.57; I2 = 0%; 2 studies, 319 participants; low CoE). We assumed an MCID of ≥ 5%. Based on 278 participants per 1000 with placebo (or no TXA) having a secondary intervention, this corresponds to 42 more (from 44 fewer to 158 more) participants with secondary interventions per 1000. Major surgical complications - Based on a representative baseline risk for major surgical complications of 4.1%, systemic TXA may reduce major surgical complications (RR 0.36, 95% CI 0.21 to 0.62; I2 = 0%; 5 studies, 733 participants; moderate CoE). We assumed an MCID of ≥ 2%. Based on 41 participants per 1000 with placebo (or no TXA) having a major surgical complication, this corresponds to 26 fewer (from 32 fewer to 16 fewer) participants with major surgical complications per 1000. Minor surgical complications - Systemic TXA may reduce minor surgical complications (RR 0.71, 95% CI 0.45 to 1.10; I2 = 76%; 5 studies, 733 participants; low CoE). We assumed an MCID of ≥ 5%. Based on 396 participants per 1000 with placebo (or no TXA) having a minor surgical complication, this corresponds to 115 fewer (from 218 fewer to 40 more) participants with minor surgical complications per 1000. Unplanned hospitalizations or readmissions - We are very uncertain how unplanned hospitalizations or readmissions are affected (RR 1.55, 95% CI 0.45 to 5.31; I2 = not applicable; 1 study, 189 participants; very low CoE). We assumed an MCID of ≥ 2%. Hospital length of stay - Systemic TXA may reduce hospital LOS (mean difference 0.52 days lower, 95% CI 0.93 lower to 0.11 lower; I2 = 98%; 7 studies, 1151 participants; low CoE). We assumed an MCID of ≥ 0.5 days. AUTHORS' CONCLUSIONS Based on 10 RCTs with substantial methodological limitations that lowered all CoE of effect, we found that systemic TXA in PCNL may reduce blood transfusions, major and minor surgical complications, and hospital LOS, as well as improve SFRs; however, it may increase AEs. We are uncertain about the effects of systemic TXA on other outcomes. Findings of this review should assist urologists and their patients in making informed decisions about the use of TXA in the setting of PCNL.

Abstract
PURPOSE OF REVIEW Percutaneous nephrolithotomy (PCNL) continues as the gold standard for the surgical management of large renal stones. This short review is intended to highlight recent publications on PCNL of all tract sizes, from mini to standard. RECENT FINDINGS Literature on PCNL in the last 2 years has focused on several main themes - decreasing complications, improving postoperative pain control, and new technology to improve outcomes. Mini-PCNL continues to prove effective and safe, with a new vacuum sheath showing promise of improving stone-free rates and decreasing infections. In terms of infections, preoperative midstream urine culture continues to be a poor indicator of postoperative infection. One of the biggest changes to PCNL practice is the reintroduction of tranexamic acid, which has shown to significantly decrease bleeding and improve outcomes. In terms of postoperative pain control, local blocks are effective and low risk. SUMMARY There are many options for surgeons when it comes to PCNL from sheath size to pain management to preoperative medication to decrease bleeding. Future research will continue to highlight, which advances are the most beneficial.

Medicine (Baltimore) 2023; 102:e34146. [PMID: 37352047 PMCID: PMC10289517 DOI: 10.1097/md.0000000000034146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 06/07/2023] [Accepted: 06/08/2023] [Indexed: 06/25/2023] Open
Abstract
BACKGROUND This meta-analysis compared the effects of intravenous Tranexamic acid (TXA) and a placebo on hemostasis, hospital course, and complications in adult patients undergoing various urologic surgeries. METHODS The literature was extensively searched using various databases. The primary outcomes were standardized mean differences (SMDs) of intraoperative blood loss and odds ratios (ORs) of necessary blood product transfusion. The secondary outcomes included SMDs of operative time, SMDs of decreased hemoglobulin levels at 24 hours after surgery, and ORs of thromboembolic events. RESULTS The meta-analysis included 13 randomized controlled trials (RCT) comprising 1814 participants in total. The SMD of intraoperative blood loss for TXA versus placebo was -0.705 (95% confidence interval [CI]: -1.113 to -0.297). The pooled ORs of transfusion in the TXA group compared with the placebo group was 0.426 (95% CI: 0.290-0.625). These findings indicated a significantly lower intraoperative blood loss and a reduced need for transfusion following intravenous TXA. The pooled ORs of thromboembolic events in the TXA group compared with the placebo group was 0.664 (95% CI: 0.146-3.024). CONCLUSIONS Intravenous TXA can reduce intraoperative blood loss, decrease the need for transfusion, and shorten operative time, and it does not increase the risk of thromboembolic events.

Abstract
This review aims to explore the postpartum hemorrhage (PPH) burden and the efficacy of prophylactic tranexamic acid (TXA) in PPH and recent indications of TXA. A comprehensive review of the literature was conducted using a combination of Medical Subject Headings keywords including "Postpartum haemorrhage," "Tranexamic acid," and "Cesarean section." PPH has been explored for epidemiology, risk factors, and pathophysiology in the first part of the article. Recent indications of TXA, obstetric indications, and the role of TXA as prophylaxis for PPH are discussed in the second part of this article. TXA has many indications apart from obstetric indications and shows a significant effect in controlling bleeding. Furthermore, TXA is more efficient in preventing PPH if administered during the final stage of labor and is a valuable option for managing obstetric bleeding.

Risk Factors for Intra-operative Bleeding in Percutaneous Nephrolithotomy in an Academic Center: A Retrospective Study. Anesth Pain Med 2022; 12:e126974. [PMID: 36937085 PMCID: PMC10016121 DOI: 10.5812/aapm-126974] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 08/04/2022] [Accepted: 08/07/2022] [Indexed: 11/16/2022] Open
Abstract
Background Percutaneous nephrolithotomy (PNL) is the treatment of choice for renal stones as a safe, effective, and minimally invasive method. However, bleeding remains a major concern in the procedure. Objectives This study aimed to investigate the risk factors of bleeding in PNL. Methods This retrospective descriptive cross-sectional study was conducted in the Urology department of Razi hospital. The data of patients with urinary calculi staghorn type who underwent PNL in a prone position under general anesthesia were recorded. A checklist including patients' demographics, surgical characteristics, and outcomes was filled out for each patient. Results The data from 151 complete files were gathered. The mean age of the cases was 47.89 ± 12.41 years. The mean hemoglobin (Hb) drop was 1.92 ± 1.56 mg/dL. At least 1 mg/dL Hb drop was observed in all cases. The highest Hb drop was 3 mg/dL.). There was no significant relationship between stone bulk, age, BMI, GFR, surgery duration, and the number of tracts, and Hb drop during PNL (P > 0.05). But there was a positive correlation between Urinary Tract Infection (UTI) history (P = 0.01) and transfusion (P = 0.0001) and Hb drop during PNL. Also, the history of open kidney surgery (P = 0.031), nephrostomy insertion (P = 0.003), and extracorporeal shock wave lithotripsy therapy (ESWL) (P = 0.041) were correlated with the increased risk of Hb drop. Conclusions Urinary tract infection, history of open surgery, nephrostomy implantation, and ESWL were significantly associated with more bleeding in PNL.

Abstract
Purpose: We performed a systematic review and meta-analysis of the literature to evaluate the efficacy of the routine use of tranexamic acid (TXA) during percutaneous nephrolithotomy (PCNL). Methods: This systematic review was conducted following the updated reporting guidelines from PRISMA 2020. Results: In total, 275 titles and abstracts were reviewed, of which 20 were screened to be eligible for full text review. Of these 20 articles, 11 were selected for inclusion after full article evaluations. Seven of these 11 studies were seen as having a low risk of bias with a Jadad score of ≥3. These studies were included for data extraction. Once data were extracted, 964 patients were included. The primary outcome, blood transfusion rate, showed significant reduction with a ratio for transfusion rate of 0.34 [95% confidence interval (CI) (0.19 to 0.61), z = 3.61, p = 0.0003]. Mean hemoglobin (Hgb) drop and operative time were both shown to be reduced with the use of TXA. The mean difference for Hgb drop was -0.86 [95% CI (-1.26 to -0.46), z = 4.23, p < 0.0001]. Reduction in operative time showed a mean difference of -8.45 minutes [95% CI (-15.04 to -1.86), z = 2.51, p = 0.01]. Stone clearance was not shown to differ significantly between experimental and control groups, with a risk ratio of 1.28 [95% CI (0.89 to 1.84), z = 1.31, p = 0.19]. Conclusions: This meta-analysis revealed that the routine use of TXA at time of PCNL reduces the rates of blood transfusion, mean Hgb drop, and operative time. With the low cost of TXA and strong safety profile, stronger consideration should be given to the routine use of TXA during PCNL by endoscopic surgeons.

Abstract
Purpose: Bleeding is the most dreadful and distressing complication of percutaneous nephrolithotomy, which can cause significant morbidity. Intravenous use of tranexamic acid to reduce bleeding complication is widely established. Our aim is to compare the result between the two groups using tranexamic acid intravenous and in irrigation solution. Materials and methods: A total of 160 patients were enrolled in this study. Patients were randomly allocated to two groups. Group 1 received 0.1% tranexamic acid solution (1000 mg in 1 L of irrigation solution (normal saline)). Group 2 received 1 g tranexamic acid intravenously in intraoperative period. Results: The mean estimated fall in haematocrit, mean estimated total blood loss and mean operative time in tranexamic acid irrigation group is significantly less compared to intravenous tranexamic acid group. No significant difference was found with regards to stone clearance. Conclusion: We found that tranexamic acid irrigation was safe and associated with reduced blood loss as compared to intravenous tranexamic acid.
